managing banners

when i put banners on my website using the banner manager under the tools in the admin panel when i place a banner on the right side of the page it stays next to the scroll bar and when the browser is resized it moves and covers features on my site. i have a banner placed along the bottom and i do not have this problem with that banner. is there any way to change this so the banner does not move when the window is resized?

Yes you can make some changes in your template files. For example  you can add table like this :

<table width="100%">

<tr>

<td><left_banner></td>

<td>main content</td>

<td><right_banner></td>

</tr>

</table>
